Torsional Fatigue and High Temperature Stiffness Modulus of Cells 3, 4, 17 & 18 of MnROAD's 1992/1993 Paving Work

The requested work called for the determination of fatigue properties of these mixes using torsional fatigue procedures. This test procedure has been described in detail in a previous report to MN DOT and the interested reader Is referred to that reports. The initial work request was to determine the fatigue properties of the mix as near the surface as impossible. During testing we were asked to also determine and compare the fatigue properties of the binder lift of each core as well. Although that work was not part of the original contract, MTE felt the information was of sufficient value in understanding the rate of fatigue development that we agreed to perform these tests at no charge to the department.
